DUMP ING-CAR. W

To all whom it may concern 3 Be it known that I, ALBERT C. MURPHY, a citizen of the United States, and resident of New York, county of New York, and State of New York, have invented an Improvement in Dumping-Cars, of which the following is a specification.

The object of my invention is to provide a construction of dumping car in which the body may rock to a tilted position whereby the contents can be discharged to the side of the track and in so doing, guide the dirt or load tothe proper distanceby use of auxiliary aprons or chute plates suitably supported and brought into operative relation by the tilting act of the body.

My object is, further, to eliminate the severe wear which has heretofore ordinarily come upon the side doors of the body when acting to guide the load being dumped and only employ said doors at time of dumping to prevent objectionable projecting of flying particles or stones, and otherwise insure the proper and most desirable distribution of the dumped contents.

My invention consists ota main frame and abody supported thereon in a manner to be rocked or tilted in a transverse direction, the said body having discharge doors hinged at their upper ends and with their sides of the body adjacent to the door portions thereof, and automatic means for causing the respective aprons or chute plates to be swnng'ontward to an inclined position acwhen being lowered.

My invention also comprchends details of construction which, together with the features above spcciiicd will he better understood by reference to theaccompanying drawings, in whichz- Figure 1 is a plan view of a' dumping car.

embodying my invention, hrolicn away at the middle to shorten its whole length in Specification of Letters Patent.

i the figure; Fig. 2 is a side elevationof the same and with protecting booths over the 'end platforms; and Fig. 3 is a transverse section of my improved car, showing the body partly in elevation.

2 is the main frame and is supported at each end by the usual .car trucks 3 of any suitable construction. The main frame may be made of girder'form and providing a plurality of transverse rocker beds 6. The body 4: is formed of sheet steel and has its under portion provided with rockers 5 Which coact with the beds 6 so that the body may rock and tilt in a transverse direction to e ther side of the main frame, one of the t lted positions being indicated in dotted lines in Fig. 3. This body is furthermore open at its sides andprovided with longitudinal metal frames 15, one at each side and forming the upper boundaries of the s de discharge openings. The open sides portion of the body are provided with doors 16 which are hinged at 17 to the metal top side frames 15 ot' the body and adapted to swing outward at the bottom when the body is tilted in dumping the load, Normally these side doors 16 are held in closed position by latches or engaging means 18 which fit over the lower edges of the doors to lock them against outward movement, except at the moment of dumpingthe load or When the body is in inclined dumping position. These latches or engaging means are preferably antom aticsintheir action and may be made as hereinafter described.

Arranged below each side of the body and hinged thereto at 2} adjacent to the floor thereof, are theaprons or chute plates 20. These plates 20 are moved up and down with the tilting body and in the act of being lowered to the dumping position their tree lower ends are swung outward to change the position of the plate from a substantially vertical position to an inclined position, as shown in full and dotted lines in Fig. 3. The means for effecting this swinging adjustment of the plates is the rocking body 4 combined with the pivoted arms 22 and connecting bars the latter hinged at one cnd to the arms and at the other to the plates 20. The arms 22 are hinged upon the longitudinal shafts 9 and are free to swing thereon in the outward direction but restrictcd in an inward direction by contacting with the main frame at 2". When the body t is in its normal horizontal position the arms 22 are all forced inward and rest against the parts 2 of the main frame2; and in the said position the aprons or chute plates 20 will preferably be slightly inclined outward at the bottom so as to put a thrust upon the arms through the aid of gravity and prevent undue lateral swinging of the plates 20 during the travel of the car.

When the car body is tilted and the dis charge side lowered, the apron or chute plate 20 at said side is also lowered; and as its axis of hinging to the body approaches the free end of the arm 22, the radial connecting bar forces the lower and free end of the plate outward into an inclinedposition, as shown in dotted lines in Fig. 3. Nhile this action is taking place on the descending side of the body, the rising of the other sidecarries the other apron or chute plate 20 upward and this action pulls upon the bars 23 and causes the free end of the arm 22 to swing around and outward, as shown'in dotted lines at the left hand side of Fig. 3. During this operation on the non-dumping side of the body, the door 16 on said side remains locked, which has the advantage of not requiring any attention when the parts are restored to the normal positions.

The rocking of the body 4: may be performed in any suitable manner, the means which I show being hand operated and well suited to the purpose; This means may be described as follows :A shaft 9 is arranged at each side of the main frame and extends longitudinally of the main frame to a position below each of the end platforms 8 (Figs. 1 and 2). These shafts 9 are journaled in lateral bracket portions 7 of the main frame 2 and are provided with pinions 10 at one or more places. Hinged to the under side of the body and at each side of the rockers are the rack bars 11 which are respectively engaged by the pinions 10 of the respective shafts 9. These rack bars are held up to the pinions by the guide rollers 12. At one end of each shaft is secured a sprocket wheel 13 and at the other end a locking wheel 14;". These wheels 13 and 14 are so arranged that one of each comes below each of the platforms 8 as shown in Fig. 1. The sprocket wheels 13 are operated by hand power means 14 which is of a reducing gear order so that a man may operate the shaft 9 which is to tilt the body into dumping position, or vice versa. The look ing wheel ll is controlled by a locking lever 14:, so that when the body is to be tilted by the hand power means 1 1 operating through one shaft 9, said shaft may be unlocked by the lever 14 at the other end of the shaft. During the normal horizontal position of the body the same may be locked in position during travel by the locking devices 1. 1 and I l at one or. both endsof the car. It will be understood that where only one body is employ ed on the car it may be operatedwholly from one end thereof and one shaft 9 employed, but in practice I prefer to employ the two shafts 9 and the other devices in respect thereto, as shown. Wheretwo shafts 9 are employed, the locking mechanism 1% and 14: may be controlled from the same platform from which the body is operated to tilt, the tilting being performed by one shaft 9 and the locking and releasing performed on the other shaft, as indicated in Fig. 1.

I do not restrict myself to any character of means for tilting or rocking the body as that may be done by hand power or otherwise in any of the ways heretofore known and understood by those skilled in the art, the means here shown and described being given by way of example only. Y

Referring now more particularly to the automatic door releasing mechanism for holding the lower ends of the doors in closed position during transport of the load and for releasing said doors in the act of dumping the load, said mechanism consists of a longitudinal rock shaft 19'at each side of the body 4 and each provided with a plu- .rality of latches or hook-shaped parts 18 which extend upward over the lower edges of the doors 16 to hold them in closed position, said shafts 19 being suitably journaled and adapted to be rocked by arms 25 secured to the shafts and arranged to be operated by links 26. These links :26 are hinged at one end to the free ends of the respective. arms of the rock shafts 19 and at the other end are pivoted at 24 to the body iwith provision fora sliding motion. The rock shafts 15) are arranged in the recess formed by the flanges of the angle irons 15 constituting the lower side girders of the body. By this arrangement of the rock shafts,the load will not be brought into contact with the shaft or its ]ournal bearings when being discharged. The aprons or chute plates 20 have their hinged supports 21 journaled \ipon these rock shafts 19, so that the hinges for the said plates 20 are also protected against injury from the discharging conto the rock shaft 19 and lower the jaws or.

latches 18 at a period approximately the termination of the downward movement of the body, thereby releasing the door 16=and allowing the Weight of the discharging load to force its way through the door opening and under the door in its releasedsposition. During its discharge, the load will pass over the inclined apron or chute plate 20 which pro ects or guides it to the proper distance from the track. When the'body is again ,righted to the horizontal position, the verious parts will assume their original posi tion shown in solid lines and the doors may be closed and latched, the latching mechanism permitting the necessary movement to enable the doors to be engaged. The weight of the bar 26 acts by gravity to rock the shaft 19 carrying the latches ldsnd hence the door 16 may close by gravity and sunnbaclr of the latches. I do not restrict myself to the automatic unlatching'niechsnism here shown, out have described it as s practical.
